Questions Flooding and drought stress are expected to increase significantly across the world plant responses these abiotic changes may be mediated by plant–plant interactions. Stress tolerance recovery often require a biomass investment that have consequences for Therefore, we questioned whether phenotypic plasticity in response flooding affected balance between competition facilitation specie...

In this paper we study a novel mathematical model with intraspecific and interspecific competition between two species consisting of non-linear parabolic–ODE–parabolic system. It describes the evolution populations in for resource, one which is subject to chemotaxis. We analyze local stability constant equilibrium solutions obtain periodic behavior solution certain data problem. For purpose, ap...

Waste from apple juice and cider industries (pomace) compares poorly against spent grains other relatively high-nutrient wastes as a substrate for bioconversion by the black soldier fly (BSF: Hermetia illucens). However, global pomace production exceeds 24 million tonnes annually novel management approaches are required to reduce waste landfill. We examined effects of BSF inoculation densities ...

Competition is a major regulatory factor in population and community dynamics. Its effects can be either direct in interference competition or indirect in exploitative competition. The impact of exploitative competition on population dynamics has been extensively studied from empirical and theoretical points of view, but the consequences of interference competition remain poorly understood. Her...

Question: How will global changes impact the ecological and evolutionary outcomes of competition? Hypothesis: Global changes that alter resource availability, such as rising atmospheric carbon dioxide (CO2) concentrations, will alter the effects of competition on mean fitness and patterns of natural selection. Because species exhibit different growth responses to elevated CO2 and because differ...

Intraspecific competition influences population and community dynamics and occurs via two mechanisms. Exploitative competition is an indirect effect that occurs through use of a shared resource and depends on resource availability. Interference competition occurs by obstructing access to a resource and may not depend on resource availability. Our study tested whether the strength of interferenc...

A Leslie-Gower-Holling type II model is modified to introduce a contagious disease in the predator population, assuming that disease cannot propagate to the prey. All the system's equilibria are determined and the behaviour of the system near them is investigated. The main mathematical issues are global stability and bifurcations for some of the equilibria, together with sufficient conditions f...
